RESUMEN

BACKGROUND: Fewer than 20% of adults with chronic gastrointestinal (GI) symptoms have accessed care to evaluate or manage their symptoms. We sought to characterize whether adults with chronic GI symptoms would use an app for symptom monitoring and the effects of participation in a digitally delivered GI chronic care program. METHODS: We provided a digital digestive care management app to adults via their employer-sponsored benefits. We evaluated participants' self-reported GI symptoms at baseline and between 30 and 90 days post-registration. GI symptoms (e.g., abdominal pain and constipation) were rated on a scale of 0 (no symptoms) to 4 (very severe symptoms). RESULTS: A total of 1936 participants were enrolled (75% female; 67% White, 11% Asian/Pacific Islander, 6% Hispanic, 7% Black; mean age: 43 years). Their most common GI conditions were irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and acid reflux. Participants of all genders and races reported statistically significant improvements in all symptoms between baseline and the end of the intervention (P < 0.05). At baseline, 79.5% of participants reported at least moderate GI symptom severity for at least one symptom. In contrast, at the end of the intervention, only 47.8% of participants reported moderate or severe symptoms, and 310 (16.0%) participants reported no symptoms. Participants who were scheduled with their care team reported greater symptom improvement than those who were not scheduled (P = 0.004). Participants reported feeling greater control of their health (83%), better management of their digestive symptoms (83%), increased happiness (76%), and greater productivity at work (54%). CONCLUSION: Demographically diverse participants engaged with a digital digestive chronic care program and reported significant improvements in digestive symptom severity.

RESUMEN

Introduction Digestive disorders, affecting 70 million people globally, have gained attention. Gastroesophageal reflux disease (GERD) causes heartburn and acid regurgitation. Factors like obesity, poor diet, and lifestyle influence its prevalence. GERD rates are higher in Saudi Arabia than in Western and East Asian countries, highlighting the need for local awareness, our study aims To assess the prevalence of local habits and risk factors of patients with GERD in the Southwest region of Saudi Arabia. Method This prospective descriptive cross-sectional online-based study included 372 individuals from the Southwest Region, Saudi Arabia. The study was conducted using a self-administrated online questionnaire to collect the data for the targeted participants. After obtaining consent to carry out the study, the data were collected and computerized using Microsoft Excel, to form a database using all the items from the data collecting sheets. Data was then encoded and analyzed using Statistical Package for Social Sciences (SPSS) software, version 27 (IBM Corp., Armonk, NY). Data was displayed and presented in the form of tables and charts Results This study included 372 individuals, predominantly Saudi 98.7%, n=367. The most common age group was 21-25 years (32.5%, n=121), followed by those over 40 (18.5%, n=69). Participants were mainly from Al-Qunfudhah and Haly 27.2%, n=101. Most were single (49.5%, n=184) or married (48.4%, n=180), with a bachelor's degree 66.7%, n=248. Employees comprised (36.3%, n=135), and students 30.9%, n=115. Only 2.7%, n=10 were pregnant. Nearly half (48.4%, n=180) had a monthly income below 5,000 SAR. Most participants weighed 40-60 kg (41.4%, n=154) and were 150-160 cm tall (47%, n=175). The prevalence of GERD was 16.1%, n=60. Significant associations were found between GERD diagnosis and meal type, smoking, family history, and high pickle and salt intake (P-values: 0.002073, 0.000607, <0.00001, and 0.008557, respectively). Conclusion This study can conclude that the prevalence of GERD is not high in the Southwest region of Saudi Arabia. Significant risk factors regarding patients' habits should be taken into consideration and diminishing them in order to decrease the incidence of the disease and improve the quality of life of already diagnosed patients.

RESUMEN

Autophagy, a conserved cellular degradation process, is crucial for various cellular processes such as immune responses, inflammation, metabolic and oxidative stress adaptation, cell proliferation, development, and tissue repair and remodeling. Dysregulation of autophagy is suspected in numerous diseases, including cancer, neurodegenerative diseases, digestive disorders, metabolic syndromes, and infectious and inflammatory diseases. If autophagy is disrupted, for example, this can have serious consequences and lead to chronic inflammation and tissue damage, as occurs in diseases such as Chron's disease and ulcerative colitis. On the other hand, the influence of autophagy on the development and progression of cancer is not clear. Autophagy can both suppress and promote the progression and metastasis of cancer at various stages. From inflammatory bowel diseases to gastrointestinal cancer, researchers are discovering the intricate role of autophagy in maintaining gut health and its potential as a therapeutic target. Researchers should carefully consider the nature and progression of diseases such as cancer when trying to determine whether inhibiting or stimulating autophagy is likely to be beneficial. Multidisciplinary approaches that combine cutting-edge research with clinical expertise are key to unlocking the full therapeutic potential of autophagy in digestive diseases.

RESUMEN

Idiopathic mesenteric phlebosclerosis (IMP) is an extremely rare disease with an unclear pathogenesis and risk factors. The clinical manifestations of IMP are mostly non-specific, mainly consisting of digestive symptoms such as abdominal pain, bloating and diarrhea. The diagnosis of IMP mainly relies on abdominal computed tomography (CT) and colonoscopy. Pathological changes associated with IMP often involve fibrous degeneration of the venous wall, which results in the thickening of the colonic wall and longitudinal calcification of the mesenteric arteries. Currently, there is no standard treatment protocol for IMP, and nonsurgical treatment is the mainstay of most medical centers. In this study, we reported a case of a 55-year-old female patient with IMP whose main clinical presentation was recurrent abdominal pain. The patient's initial diagnosis was considered an incomplete intestinal obstruction and received non-surgical treatments; however, the efficacy of the treatment was unsatisfactory. After completing abdominal CT and colonoscopy, we excluded common diseases of the digestive system (e.g., tumors, Crohn's disease), and finally considered that this patient had a high likelihood of IMP. This patient eventually underwent laparoscopic enlarged right hemicolectomy due to recurrent symptoms and poor outcomes of non-surgical treatment. Postoperative pathological results confirmed the diagnosis of IMP. During the follow-up period, the patient recovered well without recurrence of IMP. Furthermore, we have reviewed the literature related to IMP and summarized the etiology, risk factors, diagnostic methods, treatment options and prognosis of IMP.

RESUMEN

Introduction: China has experienced unprecedented transformations unseen in a century and is gradually progressing toward an emerging superpower. The epidemiological trends of digestive diseases in the United States (the US) have significant prescient effects on China. Methods: We extracted data on 18 digestive diseases from the Global Burden of Diseases 2019 Data Resource. Linear regression analysis conducted by the JoinPoint software assessed the average annual percentage change of the burden. We performed subgroup analyses based on sex and age group. Results: In 2019, there were 836.01 and 180.91 million new cases of digestive diseases in China and the US, causing 1558.01 and 339.54 thousand deaths. The age-standardized incidence rates of digestive diseases in China and the US were 58417.87/100,000 and 55018.65/100,000 respectively, resulting in age-standardized mortality rates of 81.52/100,000 and 60.88/100,000. The rates in China annually decreased by 2.149% for mortality and 2.611% for disability-adjusted life of year (DALY). The mortality and DALY rates of the US, respectively, had average annual percentage changes of -0.219 and -0.251. Enteric infections and cirrhosis and other chronic liver diseases accounted for the highest incidence and prevalence in both counties, respectively. The burden of multiple digestive diseases exhibited notable sex disparities. The middle-old persons had higher age-standardized prevalence rates. Conclusion: China bore a greater burden of digestive diseases, and the evolving patterns were more noticeable. Targeted interventions and urgent measures should be taken in both countries to address the specific burden of digestive diseases based on their different epidemic degree.

RESUMEN

Background: Microbiomes are essential components of the human body, and their populations are substantial. Under normal circumstances, microbiomes coexist harmoniously with the human body, but disturbances in this equilibrium can lead to various diseases. The oral microbiome is involved in the occurrence and development of many oral and gastrointestinal diseases. This review focuses on the relationship between oral microbiomes and oral and upper gastrointestinal diseases, and therapeutic strategies aiming to provide valuable insights for clinical prevention and treatment. Methods: To identify relevant studies, we conducted searches in PubMed, Google Scholar, and Web of Science using keywords such as "oral microbiome," "oral flora, " "gastrointestinal disease, " without any date restrictions. Subsequently, the retrieved publications were subject to a narrative review. Results: In this review, we found that oral microbiomes are closely related to oral and gastrointestinal diseases such as periodontitis, dental caries, reflux esophagitis, gastritis, and upper gastrointestinal tumors (mainly the malignant ones). Oral samples like saliva and buccal mucosa are not only easy to collect, but also display superior sample stability compared to gastrointestinal tissues. Consequently, analysis of the oral microbiome could potentially serve as an efficient preliminary screening method for high-risk groups before undergoing endoscopic examination. Besides, treatments based on the oral microbiomes could aid early diagnosis and treatment of these diseases. Conclusions: Oral microbiomes are essential to oral and gastrointestinal diseases. Therapies centered on the oral microbiomes could facilitate the early detection and management of these conditions.

1. Various microbiomes exist in the oral cavity. 2. Under normal circumstances, oral microbes and human health coexist in harmony, once this balance is broken, it may cause a variety of diseases. 3. Oral microbiota are associated with upper digestive diseases, which are expected to be an effective triage for high-risk population before endoscopic screening.

RESUMEN

BACKGROUND: The Upper Digestive Disease (UDD) Tool™ is used to monitor symptom frequency, intensity, and interference across nine symptom domains and includes two Patient-Reported Outcome Measurement Information System (PROMIS) domains assessing physical and mental health. This study aimed to establish cut scores for updated symptom domains through standard setting exercises and evaluate the effectiveness and acceptability of virtual standard setting. METHODS: The extended Angoff method was employed to determine cut scores. Subject matter experts refined performance descriptions for symptom control categories and achieved consensus. Domains were categorized into good, moderate, and poor symptom control. Two cut scores were established, differentiating good vs. moderate and moderate vs. poor. Panelists estimated average scores for 100 borderline patients per item. Cut scores were computed based on the sum of the average ratings for individual questions, converted to 0-100 scale. RESULTS: Performance descriptions were refined. Panelists discussed that interpretation of the scores should take into account the timing of symptoms after surgery and patient populations, and the importance of items asking symptom frequency, severity, and interference with daily life. The good/moderate cut scores ranged from 21.3 to 35.0 (mean 28.6, SD 3.6) across domains, and moderate/poor ranged from 47.5 to 71.3 (mean 54.5, SD 7.0). CONCLUSIONS: Panelists were confident in the virtual standard setting process, expecting valid cut scores. Future studies can further validate the cut scores using patient perspectives and collect patient and physician preferences for displaying contextual items on patient- and physician-facing dashboard.

RESUMEN

BACKGROUND: A number of observational studies indicate that insomnia is linked to inflammatory digestive diseases (IDDs). However, the definite relationship between insomnia and IDDs remains unclear. METHODS: We obtained the publicly available data from genome-wide association studies (GWAS) to conduct two-sample Mendelian randomization (MR) for association assessment. Five MR analysis methods were used to calculate the odds ratio (OR) and effect estimate, and the heterogeneity and pleiotropy tests were performed to evaluate the robustness of the variable instruments (IVs). RESULTS: One exposure and twenty outcome datasets based on European populations were included in this study. Using the inverse variance weighted method, we found insomnia was closely correlated with esophageal ulcer (OR = 1.011, 95%CI = 1.004-1.017, p = 0.001) and abdominal pain (effect estimate = 1.016, 95%CI = 1.005-1.026, p = 0.003). Suggestive evidence of a positively association was observed between insomnia and duodenal ulcer (OR = 1.006, 95%CI = 1.002-1.011, p = 0.009), gastric ulcer (OR = 1.008, 95%CI = 1.001-1.014, p = 0.013), rectal polyp (OR = 1.005, 95%CI = 1.000-1.010, p = 0.034), haemorrhoidal disease (OR = 1.242, 95%CI = 1.004-1.535, p = 0.045) and monocyte percentage (effect estimate = 1.151, 95%CI = 1.028-1.288, p = 0.014). No correlations were observed among other IDDs, phenotypes and biomarkers. CONCLUSIONS: Our MR study assessed the relationship between insomnia and IDDs/phenotypes/biomarkers in depth and revealed potential associations between insomnia and ulcers of the esophagus and abdominal pain.

RESUMEN

INTRODUCTION: The aim of this study is to estimate the global burden of pancreatic cancer from 1990 to 2019. METHODS: We reconstructed the Global Burden of Diseases (GBD) study results for pancreatic cancer across 204 countries and territories. Our study generated estimates for key disease burden indicators, including incidence, prevalence, mortality, and disability-adjusted life years (DALYs), and cost. Linear regression analysis of the natural logarithm of age-standardized outcomes was used to calculate annual percent change. RESULTS: In 2019, there were a total of 530,296 incident and 442,101 prevalent cases of pancreatic cancer, resulting in 531,107 deaths and 11.5 million DALYs lost. The age-standardized incidence and prevalence of pancreatic cancer has increased from 5.22 (95% CI 4.97-5.40) to 6.57 (CI 6.00-7.09) per 100,000 people per year, and 4.1 (95% CI 3.95-4.26) to 5.4 (CI 4.96-5.87), respectively. This equated to 10 million (95% CI 9.5 to 10.4 million) incident cases of pancreatic cancer. The number of DALYs lost as a result of pancreatic cancer was 225 million years (95% CI 216-234 million years). Mortality from pancreatic cancer increased over the study period from 3.7 (95% CI 3.54-3.83) to 6.9 (95% CI 6.36-7.32). Incidence, prevalence, DALYs, and mortality were higher in countries with a higher socio-demographic index. CONCLUSIONS: Pancreatic cancer is rising around the world and is associated with a high economic burden. Programs aimed at reducing modifiable risk factors are needed.

RESUMEN

BACKGROUND: Gastric cancer (GC) has high morbidity and mortality. Moreover, because GC has no typical symptoms in the early stages, most cases are already in the advanced stages by the time the symptoms appear, thus resulting in poor prognosis and a low survival rate. Endoscopic submucosal dissection (ESD) can realize the early detection and diagnosis of GC and become the main surgical method for early GC. However, ESD has a steep learning curve and high technical skill requirements for endoscopists, which is not conducive to its widespread implementation and advancement. Therefore, a series of auxiliary techniques have been derived. AIM: To evaluate the safety and efficacy of magnetic anchor technique (MAT)-assisted ESD in early GC. METHODS: This was an ex vivo animal experiment. The experimental models were the isolated stomachs of pigs, which were divided into two groups, namely the study group (n = 6) with MAT-assisted ESD and the control group (n = 6) with traditional ESD. Comparing the total surgical time, incidence of surgical complications, complete mucosal resection rate, specimen size, and the scores of endoscopist's satisfaction with the procedure reflected their feelings about convenience during the surgical procedure between the two groups. The magnetic anchor device for auxiliary ESD in the study group comprised three parts, an anchor magnet (AM), a target magnet (TM), and a soft tissue clip. Under gastroscopic guidance, the soft tissue clip and the TM were delivered to the pre-marked mucosal lesion through the gastroscopic operating hole. The soft tissue clip and the TM were connected by a thin wire through the TM tail structure. The soft tissue clip was released by manipulating the operating handle of the soft tissue clip in a way that the soft tissue clip and the TM were fixed to the lesion mucosa. In vitro, ESD is aided by maneuvering the AM such that the mucosal dissection surface is exposed. RESULTS: The total surgical time was shorter in the study group than in the control group (26.57 ± 0.19 vs 29.97 ± 0.28, P < 0.001), and the scores of endoscopist's satisfaction with the procedure were higher in the study group than in the control group (9.53 ± 0.10 vs 8.00 ± 0.22, P < 0.001). During the operation in the study group, there was no detachment of the soft tissue clip and TM and no mucosal tearing. The magnetic force between the AM and TM provided good mucosal exposure and sufficient tissue tension for ESD. The mucosal lesion was completely peeled off, and the operation was successful. There were no significant differences in the incidence of surgical complications (100% vs 83.3%), complete mucosal resection rate (100% vs 66.7%, P = 0.439), and specimen size (2.44 ± 0.04 cm vs 2.49 ± 0.02, P = 0.328) between the two groups. CONCLUSION: MAT-ESD is safe and effective for early GC. It provides a preliminary basis for subsequent internal animal experiments and clinical research.

RESUMEN

Japan is becoming a superaged society, and nutrition therapy for the elderly population is very important. Elderly individuals often have multiple diseases and are prone to malnutrition. Furthermore, functional constipation, diarrhoea, faecal incontinence, etc., may occur despite no organic abnormality of digestive tract function. Due to these disabilities, the resulting malnutrition, and the slow recovery, it is often difficult for elderly individuals to reintegrate into society. Secondary or incorrect nutritional management increases complications, decreases physical function and worsens the prognosis. Previous statistical research suggests that in-hospital mortality is significantly higher among hospitalised patients aged ≥65 years who ingest less than half of their caloric needs. Therefore, appropriate nutritional management from an early stage is essential for elderly individuals. Moreover, functional excretion disorders, dementia, and sarcopenia (muscle-wasting disease) are attracting attention as pathological conditions unique to elderly individuals, and it is essential to undergo rehabilitation early with nutritional management. Being elderly does not preclude nutritional management, and it is necessary to reconsider appropriate nutritional therapy even in the terminal stage and in advanced physical and mental illnesses. This review explores the relationship between dietary intake and FGIDs, with a focus on elderly adults.

RESUMEN

IgG4-related digestive diseases encompass a group of chronic inflammatory disorders characterized by autoimmune reactions and fibrosis affecting multiple digestive organs. These diseases are identified by elevated serum levels of IgG4 and the presence of IgG4-positive plasma cell infiltration in the affected sites, along with storiform fibrosis, obliterative phlebitis, and eosinophilic infiltration. Although extensive research has been conducted, a comprehensive understanding of these conditions remains elusive. Current clinical diagnosis often relies on the application of integrated diagnostic criteria for IgG4-related diseases, combined with specific organ involvement criteria. Distinguishing them from malignancies poses considerable challenges. Moreover, further investigations are required to elucidate the underlying pathogenic mechanisms and explore potential therapeutic interventions. This review provides a systematic classification of IgG4-related digestive diseases while discussing their diagnostic strategies, clinical presentations, and treatment modalities. The comprehensive insights shared herein aim to guide clinicians in their practice and contribute to the advancement of knowledge in this field.

RESUMEN

OBJECTIVES: This meta-analysis aims to examine the general mortality risk and specific mortality risk of gout, as the incidence of the condition is on the rise but information on mortality rates remains uncertain. METHOD: The researchers conducted a search of published cohort studies on gout and mortality using Medical subject headings and keywords in PubMed, EMBASE, and Cochrane Library databases from inception to September 2022. The quality of study was evaluated using the NOS scale. Statistical analysis was performed using STATA software (version 16.0). Publication bias was assessed using funnel plots and Egger's test. RESULT: This meta-analysis included 11 cohort studies (2010-2022), covering 14,854,490 people with a follow-up time of 1.66-16 years. The pooled analysis shows increased risk of overall mortality [HR=1.23, 95 % CI (1.13-1.35), I2=96.4 %, P<0.001], cardiovascular mortality [HR=1.29, 95 % CI (1.13-1.48), I2=98.5 %, P<0.001], infection mortality [HR=1.24, 95 % CI (1.04-1.47), I2=88.5 %, P = 0.019], and digestive system disease mortality [HR=1.42, 95 % CI (1.13-1.80), I2=91.7 %, P = 0.003] in gout. Sensitivity and subgroup analysis support the findings, and publication bias was not evident. CONCLUSION: The findings from our meta-analysis indicate that gout is associated with an increased risk of all-cause mortality, as well as mortality related to cardiovascular disease, infections, and digestive system diseases. This has important implications for clinical practice, nursing care of patients with gout, and guidance on lifestyle modifications to prevent adverse outcomes such as cardiovascular events, infections, and digestive disorders.

RESUMEN

BACKGROUND: Disturbances in the intestinal barrier and gut dysbiosis have been observed in patients with functional bowel diseases. AIMS: To investigate the correlation between biomarkers of intestinal barrier disorders at different layers and the severity of symptoms in patients with overlapping diarrhea-predominant irritable bowel syndrome and functional dyspepsia (IDFO), as well as with gut microbiota taxa. METHODS: This study included 45 patients with IDFO and 16 healthy controls. Endoscopy with biopsy of the duodenum and sigmoid colon (SC) was performed to count intraepithelial lymphocytes (IELs) and mucosal eosinophils (subepithelial layer), assess fatty acid binding protein (FABP; epithelial layer) level, and stain for mucin-2 (MUC-2; pre-epithelial layer). Composition of the gut microbiota was evaluated using 16S rRNA gene sequencing. RESULTS: Patients with IDFO exhibited an increase in biomarkers of intestinal barrier disorders at all layers studied. IEL count in the duodenum was correlated with the severity of bloating (r = 0.336; p = 0.024) and, in the SC, was correlated with tenesmus severity (r = 0.303; p = 0.042). FABP-1 level in the SC was correlated with the severity of diarrhea (r = 0.577; p = 0.001), and FABP-5 concentration in the SC was correlated with abdominal distension (r = 0.477; p = 0.010). MUC-2 concentration in the duodenum was correlated with the severity of heartburn (r = 0.572; p = 0.025) and burning sensation in the epigastrium (r = 0.518; p = 0.048). All biomarkers of intestinal barrier permeability were correlated with the abundance of some gut microbiota taxa. CONCLUSION: Patients with IDFO exhibited disrupted intestinal barrier function in all layers, which was associated with clinical symptom severity and changes in the gut microbiota.

RESUMEN

BACKGROUND & AIMS: This study assessed the worldwide burden of digestive diseases between 1990 and 2019. METHODS: We analyzed data from the Global Burden of Diseases study, covering 18 digestive diseases across 204 countries and territories. Key disease burden indicators, including incidence, prevalence, mortality, and disability-adjusted life years (DALYs), were studied. Linear regression analysis was applied to the natural logarithm of age-standardized outcomes to determine the annual percent change. RESULTS: In 2019, there were 7.32 billion incidents and 2.86 billion prevalent cases of digestive diseases, resulting in 8 million deaths and 277 million DALYs lost. Little to no decrease in global age-standardized incidence and prevalence of digestive diseases was observed between 1990 and 2019, with 95,582 and 35,106 cases per 100,000 individuals in 2019, respectively. The age-standardized death rate was 102 per 100,000 individuals. Digestive diseases accounted for a significant portion of the overall disease burden, with more than one-third of prevalent cases having a digestive etiology. Enteric infections were the primary contributor to incidence, death, and DALYs lost, whereas cirrhosis and other chronic liver diseases had the highest prevalence rate. The burden of digestive diseases was inversely related to the sociodemographic index, with enteric infections being the predominant cause of death in low and low-middle quintiles and colorectal cancer in the high quintile. CONCLUSIONS: Despite significant reductions in deaths and DALYs due to digestive diseases from 1990 to 2019, they remain prevalent. A significant disparity in the burden of digestive diseases exists among countries with different development levels.

RESUMEN

OBJECTIVE: Observing the impact of the coronavirus disease 2019 (COVID-19) pandemic on digestive diseases in hospitalized patients at the Department of Gastroenterology-Hepatology in "Mother Teresa" University Hospital Center (UHC),Tirana. METHODS: This retrospective study was carried out from June 2020 to December 2021 involving 41 cases of patients >18 years who were positive for COVID-19 infection detected by RT-PCR (Reverse Transcription-Polymerase Chain Reaction) assays of nasopharyngeal swab specimens. The severity of COVID-19 infection was evaluated by hematological/biochemical parameters, blood oxygenation/need for oxygen, radiological data on pulmonary CT imaging. RESULTS: Out of 2527 hospitalized cases, 1.6% (41) were positive for the infection. The average age was 60.05 +/- 15.008 years. The group of age with more patients (48.8%) was 41-60 years. Infected males were higher than females (p<0.001). Out of the total, 21% were vaccinated at the diagnosis. Most patients came from urban areas, more than a half from the capital. Frequency of the digestive diseases was: cirrhosis 31.7%, pancreatitis 21.9%, alcoholic liver disease 21.9%, gastrointestinal hemorrhage 19.5%, digestive cancer 14.6%, biliary diseases 7.3%, inflammatory bowel disease (IBD) 2.4%, other digestive diseases 4.8%. Fever (90%) and fatigue (78.04%) were the dominant clinical signs.  Biochemical and hematological parameters showed elevation of average value of aspartate amino transferase (AST), alanine transaminase (ALT) (AST>ALT, p<0.001), and bilirubin in all the patients. Higher levels of creatinine and significantly predictive value of systemic inflammation indices NLR (neutrophil to lymphocyte ratio ) and MLR (monocyte to lymphocyte ratio) were found in the fatality cases. Patients with cirrhosis had more severe form of COVID-19, lower blood oxygenation and needed treatment by O2-therapy (p<0.046). Death rate was 12%. A strong correlation was found between the need for O2-therapy and deaths (p<0.001) and between characteristic findings for COVID-19 in pulmonary CT imaging and low blood oxygenation (p<0.003). CONCLUSION: Comorbidity with chronic diseases, such as liver cirrhosis, has an important impact on the severity and mortality of the patients with COVID-19 infection. Inflammatory indices, such as NLR (neutrophil to lymphocyte ratio) and MLR (monocyte to lymphocyte ratio), are useful tools in predicting the evolution toward severe forms of the disease.

RESUMEN

The development of medicine has shifted from empirical medicine to evidence-based medicine, providing more scientific and precise clinical evidence for the diagnosis and treat-ment of human diseases, and to guide clinical practice and bring benefits to patients. However, there are still some diseases for which it is difficult to obtain large-scale evidence-based medical evidence for various reasons, especially some rare diseases and difficult and serious diseases. These rare diseases and difficult and serious diseases are often difficult to diagnose and treat in clinical practice, and need guidance and advice from highly qualified experts, thus, various expert consensuses have emerged. The authors analyze the recent expert consensus in the field of digestive diseases at home and abroad, and focus on the methods and pathways for the development of the international common clinical expert consensus. It is proposed that the current stage is in line with China's national condi-tions, based on the international perspective, and mastering the international consensus Delphi pathway, in order to further standardizing the method of developing expert consensus in the clinical field of China, significantly improve the academic level of expert consensus in China, provide scientific, standardized, and international-level expert consensus for the majority of clinical workers, and finally serve the majority of patients and ultimately serving clinical patients.

RESUMEN

Objective:To study the correlation between nutritional status and length of hospital stay in patients with digestive disorders.Methods:The data were collected from the database of a multi-center investigation on the dynamic changes of nutritional status of hospitalized patients in China, a project led by the Geriatric Nutrition Support Group, Society of Parenteral and Enteral Nutrition, Chinese Medical Association. The enrolled patients were screened for malnutrition and possible sarcopenia using Global Leadership Initiative on Malnutrition criteria, and the dynamic changes of serum biochemical indexes during hospital stay and the effects of malnutrition and possible sarcopenia on the length and cost of hospital stay were analyzed.Results:A total of 1 180 patients were enrolled, with an average age of (56.3±16.1) years, the average height of (164.65±8.29) cm, and the average weight of (62.12±12.12) kg. There were significant differences in body weight, body mass index, calf circumference, lymphocyte count, triglyceride, hemoglobin, albumin and total protein between at discharge and at admission ( P<0.001). There might be a correlation between post-admission malnutrition and sarcopenia. There was neither significant difference in the proportion of patients with malnutrition at admission among different age groups ( P=0.438), nor in that at discharge among different age groups ( P=0.439). The proportion of patients with malnutrition showed no significant difference between subgroups with patients<65 years old and ≥ 65 years old, at admission and discharge ( P>0.05). However, comparison of the proportion of patients with sarcopenia between subgroups with patients<65 years old and ≥65 years old displayed significant differences at admission and discharge ( P<0.001), but not the comparison of the proportion of patients with possible sarcopenia ( P>0.05). The length of hospital stay in patients with malnutrition was significantly longer than that in patients without malnutrition [(13.22±6.24) days vs. (12.08±5.25) days, P<0.001]. The length of hospital stay of patients with and without sarcopenia was also significantly different [(12.87±5.93) days vs. (12.02±5.22) days, P<0.001). Patients with concurrent malnutrition and sarcopenia had longer hospital stay [(14.57±7.15) days vs. (12.07±5.22) days, P<0.001], and higher medical cost [(2.78±2.19) ten thousand Chinese Yuan vs. (2.24±2.33) ten thousand Chinese Yuan, P<0.05)] compared with those without concurrent malnutrition and sarcopenia. Conclusions:A large proportion of patients with digestive disorders were diagnosed with malnutrition and/or possible sarcopenia during hospitalization. There is possible correlation between malnutrition and possible sarcopenia, and both can lead to a longer hospital stay and higher medical cost.

RESUMEN
